Well, isn't that a happy little question! When we have a variable like y and we add 4 to it, we simply combine y with 4 to make y + 4. It's like adding a few extra trees to our painting to make it even more beautiful. Just remember, there are no mistakes, only happy accidents in math and art.

y2 + 8y + 16 = y2 + 4y + 4y + 16 = y(y + 4) + 4(y + 4) = (y + 4)(y + 4) or (y + 4)2
x = 0 and y = 4
xy plus 2x plus 4y plus 8 or (xy+2x) + (4y+8) or x(y+2) + 4(y+2) or (x+4)(y+2)
y2 +8y + 16 = 0 can factor to (y+4) (y+4) = 0 so y+4 = 0 so y = -4
If you mean y+10 = 4 then the value of y is -6
They are expressions.
If Y and y are the same, then it is -y + 4 or 4 - y.
The answer is y = -3x -4.
y2 + 8y + 16 = y2 + 4y + 4y + 16 = y(y + 4) + 4(y + 4) = (y + 4)(y + 4) or (y + 4)2
(-y+4)+ (9y-6) (9y-y) + (4-6) 8y - 2
y=4
It is equivalent to x + y + 4.
The value of Y in the equation 4-y plus 6 = 45 is -35.
8y/y + 2 + 16/y + 2 = 8 + 2 + 16/y +2 = 12 + 16/y = 4(3 + 4/y) or 4/y*(3y + 4)
y=4
x = 0 and y = 4
xy plus 2x plus 4y plus 8 or (xy+2x) + (4y+8) or x(y+2) + 4(y+2) or (x+4)(y+2)
